Abstract:
A numerical model is developed and implemented into the open-source CFD-code OpenFOAM to predict the formation and thickness of composite layers, which grow during the composite casting of Cu and Al. The growth of AlxCuy phases is calculated based on a reaction-diffusion model, comprising the elements diffusion, thermodynamic properties and reaction rates at the phase boundaries. The influence of melt flow on the composite layer structure is considered by advection of intermetallic phases during...     »
